Ange Postecoglou admitted he is being given every support by the club in his bid to strengthen the Celtic squad in January.
And the Hoops boss said some players will be heading for a permanent Parkhead exit with others going out on loan next month.
Postecoglou says he is pleased with the progress made and squad building since arriving this summer.
But the Aussie knew in the summer that he needed more despite bringing in 12 players as he confessed it would have been too much to bring in any more than a dozen at the one time.
Reo Hatate already looks certain to arrive from the J-League market the Celtic boss knows so well.
Ahead of the visit of Hearts to Parkhead, Postecoglou said: “I still think we need more as squad-wise, we are not where we want to be.
“It’s only natural that we wouldn’t be. We’ve added 12 players and it would have been too much to bring in any more than that.
“I knew at the end of the transfer window that it still wasn’t enough. Nothing has changed although I’m really pleased we have managed to get through this period thus far.
“We’ve got a lot of games to go and most of the players are up and running and available.
“We are starting to get to a good level. The resilience we showed coming back from Germany and playing three days later is a good sign for the team as well.
“My view is that we can still improve the squad and we want to improve the squad in January and the club is supporting me in that.
“Some guys will be going on loan and some will be moving out, that’s only natural as everything progresses.
“Some of that will depend on the players themselves and where they feel they are at.
“Circumstances change and I expect some players will be moving on.”
